Bag-ohay lang, hingpit namong nahuman ang produksyon alang sa usa ka batch sa hepa filters ug ulpa filters nga ihatod sa Singapore sa dili madugay. Each filter must be tested before delivery according to EN1822-1, GB/T13554 and GB2828 standard. The test content mainly include overall size, filter core and frame material, rated air volume, initial resistance, leakage test, efficiency test, etc. Each filter has an exlusive serial number and you can see it on its lable pasted on filter frame.
